Colin Walters 6873650cae lib/sysroot: Add OSTREE_EX_STAGE_DEPLOYMENTS environment variable
I feel like I'm drowning in a pile of experimental-but-almost-stable
features...

Anyways, since we made the feature opt-in in rpm-ostree in
https://github.com/projectatomic/rpm-ostree/pull/1352
let's mirror that a bit here with an environment variable so people
can play with it more easily.

The tests needed some tweaks; specifically we need to reload the
status fact after making changes.  I'm still a bit uncertain
about the Ansible-as-tests.

But we add an upgrade test that uses the new environment variable.

Colin Walters 579faf92fd tests: Fix installed tests more
OK so I noticed that something was failing and we were missing
`set -xeuo pipefail` in our shells.  That of course revealed
the ansible tests didn't actually work - my only defense
here is spending so much time fighting to get it through CI
and trying something new.

Anyways, to make the staged-deploy tests work we need a task
that actually uses `rpm-ostree override` rather than `usroverlay`.

Let's make this a bit saner and have a clean split between
tests that are "shell-script+usroverlay" and "ansible+override".

Colin Walters 5337ba51b2 lib/deploy: Do post-ops when removing staged commit
These are further fixes based on running more of the rpm-ostree
test suite.

When dropping the staged deployment, we do need to do the
"post operations" such as bumping the sysroot mtime, so that
clients know something changed.  We also need to regenerate
the deployment refs.  And of course do a sysroot reload.

Also, add a "base cleanup" after creating a staged deployment
which also regenerates the refs.

There's no reason to do this.  I didn't actually hit this problem,

Colin Walters 8c1542134c lib/repo: Enable locking by default, but drop external API
The code has been sitting around for a while but since I disabled
it by default, I doubt anyone is really using it or relying on it.

This patch and turns on locking by default, and also drops the
API which was only public in the experimental API builds.
Conceptually these are two distinct things, and we
may actually want to split up the patches.

I don't think this will break anyone, but it's hard to say for sure.
It's also going to be hard to find out until we actually release
I suspect...

But anyone who is broken should be able to add `locking=false` into
their repo config.  On the flip side Endless has been shipping with
this enabled and it is reported to help.

The reason to drop the APIs: I'm a bit concerned about the interactions over time
between libostree's use of the API and any apps that start using it.
For example, if an app specifies a SHARED lock in their code, then
later internally we decide to temporarily grab an `EXCLUSIVE`, but the
app had a second thread/process that was `EXCLUSIVE` already, and
that process was waiting on the first bit of code, then we could
deadlock. I can't think of a real world situation where this would happen
yet though.

We are likely to in the future have say `fsck` take an external lock,
`checkout` grab a shared one, etc.

Colin Walters 06d39efcb5 bin/deploy: Avoid loading merge deployment kargs unless necessary
The fact that `ostree admin deploy` always itself loaded the
merge kargs masked a bug in the core.  Let's change our tests
to not pass any kernel arguments to ensure we cover this.

The new logic in the CLI is a bit subtle, but if you read
carefully is a lot clearer I believe.  Basically we have one
of a few "starting points" in the first section, which can
then be further augmented.

Matthew Leeds cf78888401 create-usb: Update summary in destination repo
Currently the create-usb command only generates a summary file in the
destination repo if one doesn't already exist, which means if one does
exist it becomes out of date after the new refs are pulled. This commit
makes ostree regenerate the summary regardless of whether it exists, so
that consumers such as ostree_repo_find_remotes_async() (and at a higher
level, GNOME Software) get an accurate picture of the refs available on
the mount. This commit also updates one of the unit tests to check that
the summary is accurate after a second pull into the same repo.

Since any user of the create-usb command is using collection IDs they
are new enough to be using the unsigned summary support. While it would
technically be possible to use summary signatures on a repo and use the
create-usb command on it (a scenario broken by this commit), the
create-usb command is designed for P2P distribution of refs, which
requires use of unsigned summary support. So this is a legitimate
narrowing of the tool.

Colin Walters 16d3359bf8 lib/sysroot: Move staged into deployment list, rework handling
Followup to: https://github.com/ostreedev/ostree/pull/1503
After starting some more work on on this in rpm-ostree, it is
actually simpler if the staged deployment just shows up in the list.

It's effectively opt-in today; down the line we may make it the default,
but I worry about breaking things that e.g. assume they can mutate
the deployment before rebooting and have `/etc` already merged.

There's not that many things in libostree that iterate over the deployment
list.  The biggest change here is around the
`ostree_sysroot_write_deployments_with_options` API.  I initially
tried hard to support a use case like "push a rollback" while retaining
the staged deployment, but everything gets very messy because that
function truly is operating on the bootloader list.

For now what I settled on is to just discard the staged deployment;
down the line we can enhance things.

Where we then have some new gymnastics is around implementing
the finalization; we need to go to some effort to pull the staged
deployment out of the list and mark it as unstaged, and then pass
it down to `write_deployments()`.

Colin Walters eb506c759c Add concept of "staged" deployment
Add API to write a deployment state to `/run/ostree/staged-deployment`,
along with a systemd service which runs at shutdown time.

This is a big change to the ostree model for hosts,
but it closes a longstanding set of bugs; many, many people have
hit the "losing changes in /etc" problem.  It also avoids
the other problem of racing with programs that modify `/etc`
such as LVM backups:
https://bugzilla.redhat.com/show_bug.cgi?id=1365297

We need this in particular to go to a full-on model for
automatically updated host systems where (like a dual-partition model)
everything is fully prepared and the reboot can be taken
asynchronously.

Matthew Leeds cb3360fca6 lib/repo: Add timestamps to OstreeRepoFinderResult
Currently OstreeRepoFinderResult, a data structure used by pull code
that supports P2P operations, has a hash table mapping refs to checksums
but doesn't include timestamp information. This means that clients have
no way of knowing just from the OstreeRepoFinderResult information if a
commit being offered by a peer remote is an update or downgrade until
they start pulling it. The client could check the summary or the commit
metadata for the timestamps, but this requires adding the temporary
remotes to the repo config, and ostree is already checking timestamps
before returning the results, so I think it makes more sense for them to
be returned rather than leaving it to the client. This limitation is
especially important for offline computers, because for online computers
the latest commit available from any remote is the latest commit,
period.

This commit adds a "ref_to_timestamp" hash table to
OstreeRepoFinderResult that is symmetric to "ref_to_checksum" in that it
shares the same keys. This is an API break, but it's part of the
experimental API, and none of the current users of that (flatpak,
eos-updater, and gnome-software) are affected. See the documentation for
more details on "ref_to_timestamp". One thing to note is the data
structure currently gets initialized in find_remotes_cb(), so only users
of ostree_repo_find_remotes_async() will get them, not users of, say,
ostree_repo_finder_resolve_all_async(). This is because the individual
OstreeRepoFinder implementations don't currently access the timestamps
(but I think this could be changed in the future if there's a need).

This commit will allow P2P support to be added to
flatpak_installation_list_installed_refs_for_update, which will allow
GNOME Software to update apps from USB drives while offline (it's
already possible online).

As part of this I split off a "libpaprci" which I intend to maintain
as a "copylib" for a little bit between ostree/rpm-ostree, and then
we'll figure out how to expand from there (maybe some of the patterns
get "baked in" to PAPR for example).

Giuseppe Scrivano 127d8bb846 commit: add logic for .payload-link
When a new object is added to the repository, create a
$PAYLOAD-SHA256.payload-link symlink file as well.  The target of the
symlink is the checksum of the object that was added the repository.

Whenever we add a new object file, in addition to lookup if the file is
already present with the same checksum we also check if an object with
the same payload is in the repository.

If a file with the same payload is already present in the repository, we
copy it with `glnx_regfile_copy_bytes` that internally attempts to
create a reflink (ioctl (..., FICLONE, ..)) to the target file if the
file system supports it.  This enables to have objects that share the
payload but have a different inode and xattrs.

By default the payload-link-threshold value is G_MAXUINT64 that disables
the feature.

Colin Walters 0041a7a1ed core: Add API (and standard concept for) content checksum
There are a few cases for knowing whether a commit has identical
content to another commit.  Some people want to do a "promotion workflow",
where the content of a commit on a tesitng branch is then "promoted"
to a production branch with `ostree commit --tree=ref`.

Another use case I just hit in rpm-ostree deals with
[jigdo](https://github.com/projectatomic/rpm-ostree/issues/1081) where we're
importing RPMs on both the client and server, and will be using the
content checksum, since the client/server cases inject different metadata
into the commit object.

Jonathan Lebon 2e95e06616 lib/checkout: add filter API to skip over files
This is analogous to the filtering support for the commit API: we allow
library users to skip over checking out specific files. This is useful
in some tricky situations where we *know* that the files to be checked
out will conflict with existing files in subtle ways.

One such example is in rpm-ostree support for multilib. There, we want
to allow checking out a package onto an existing tree, but skipping over
files that are not coloured to our preferred value (e.g. not overwriting
an i686 version of `ldconfig` if we already have the `x86_64` version).

Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
  text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
  environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the

William Manley 720e2ec9bc Add support for devicetree files alongside the kernel and initramfs
Much like the (optional) initramfs at
`/usr/lib/ostree-boot/initramfs-<SHA256>` or
`/usr/lib/modules/$kver/initramfs` you can now optionally include a
flattened devicetree (.dtb) file alongside the kernel at
`/usr/lib/ostree-boot/devicetree-<SHA256>` or
`/usr/lib/modules/$kver/devicetree`.

This is useful for embedded ARM systems which need the devicetree file
loaded by the bootloader for the kernel to discover and initialise
hardware.  See https://en.wikipedia.org/wiki/Device_tree for more
information.

This patch was mostly produced by copy-pasting code for initramfs handling
and renaming `s/initramfs/devicetree/g`.  It's not beautiful, but it is
fairly straightforward.

It may be useful to extend device-tree support in a number ways in the
future.  Device trees dependant on many details of the hardware they
support.  This makes them unlike kernels, which may support many different
hardware variants as long as the instruction-set matches.  This means that
a ostree tree created with a device-tree in this manner will only boot on
a single model of hardware.  This is sufficient for my purposes, but may
not be for others'.

I've tested this on my NVidia Tegra TK1 device which has u-boot running
in syslinux-compatible mode.

Colin Walters 8e6e64a5ad lib: Validate metadata structure more consistently during pull
Previously we were doing e.g. `ot_util_filename_validate()` specifically inline
in dirtree objects, but only *after* writing them into the staging directory (by
default). In (non-default) cases such as not using a transaction, such an object
could be written directly into the repo.

A notable gap here is that `pull-local --untrusted` was *not* doing
this verification, just checksums.  We harden that (and also the
static delta writing path, really *everything* that calls
`ostree_repo_write_metadata()` to also do "structure" validation
which includes path traversal checks.  Basically, let's try hard
to avoid having badly structured objects even in the repo.

One thing that sucks in this patch is that we need to allocate a "bounce buffer"
for metadata in the static delta path, because GVariant imposes alignment
requirements, which I screwed up and didn't fulfill when designing deltas. It
actually didn't matter before because we weren't parsing them, but now we are.
In theory we could check alignment but ...eh, not worth it, at least not until
we change the delta compiler to emit aligned metadata which actually may be
quite tricky.  (Big picture I doubt this really matters much right now
but I'm not going to pull out a profiler yet for this)

The pull test was extended to check we didn't even write a dirtree
with path traversal into the staging directory.

There's a bit of code motion in extracting
`_ostree_validate_structureof_metadata()` from `fsck_metadata_object()`.

Then `_ostree_verify_metadata_object()` builds on that to do checksum
verification too.

Colin Walters 2b78df25f4 tests: Add a test case for path traversal in a dirtree
I was reading about a recent security issue with both EMC and VMWare:
https://arstechnica.com/information-technology/2018/01/emc-vmware-security-bugs-throw-gasoline-on-cloud-security-fire/

It's a classic path traversal problem, and that made me think more about our
handling of this in libostree.  Fortunately of course, not being new to
this rodeo, long ago I *did* consider path traversal.  Inside the pull
code, we call `ot_util_filename_validate()`.  Also, `fsck` does this too.

I have further followups here, but let's add some test cases for this. I crafted
a repository with a `../` in a dirtree object by patching libostree to inject
it, and that's included as a tarball.

This patch covers the two cases where we do already have checks; pulling
via HTTP, and in `fsck`.

Gatis Paeglis 4233b1db19 Support for booting without initramfs
Previously when initramfs-* was not found in a deployment's

ostree booting by a kernel patch.

With this patch, the behaviour changes to be - if initramfs-*
is not found, assume that system is using a static
ostree-prepare-root as init process. Booting without initramfs
is a common use case on embedded systems. This approach is
also more convenient, than having to patch the kernel.

Jonathan Lebon 939791b4fa bin/commit: add --keep-metadata option
Clients of libostree such as rpm-ostree make extensive use of the
`ostree commit -b foo --tree=ref=foo` pattern in their tests, e.g. to
simulate an update.

What I'm trying to solve here is that it's often the case that we want
to keep metadata from the previous commit without having to be too
verbose (i.e. reading from the parent, then passing it as an argument).

The new `--keep-metadata` switch makes this really easy. I intend to use
this in the rpm-ostree testsuite to make sure we always carry over the
`source-title` metadata as well as during set up for tests that require
`rpmostree.rpmdb.pkglist` metadata.

I initially implemented this in a small wrapper script that uses the API
directly, though we make use of so many other `ostree commit` functions
that it'd require re-implementing a lot of it.

Colin Walters 73d910e82e Add public API for fsck, use it before loading metadata
A while ago I did `truncate -s 0 /path/to/repo/00/123.commit`, and expected a
checksum error, but I actually got a validation error due to us loading the
commit into a variant and trying to parse out the parent checksum, etc.

I first started by changing the `load_and_fsck_one_object()` function to
checksum before loading, but the problem is that we do a traverse of all objects
first. Fixing this is going to require an `OSTREE_REPO_COMMIT_TRAVER_FLAG_FSCK`
or something.

In the meantime at least though, let's add a public API to fsck a single object
which *does* checksum cleanly before parsing the object, and change the `fsck`
command to use it.

We then change the fsck binary to do this while iterating over the refs
and finding the commit object.  This way we'll at least get a checksum
first for commit objects, even if not dirtree/dirmeta.

Colin Walters 7c8ea25306 lib/repo: Add a DEVINO_CANONICAL commit modifier flag
I was seeing the `Writing OSTree commit...` phase of rpm-ostree
being very slow lately.  This turns out to be more fallout from
https://github.com/ostreedev/ostree/pull/1170
AKA commit: 8fe4536

Loading the xattrs is slow on my system (F27AW, XFS+LVM, NVMe). I haven't fully
traced through why, but AIUI at least on XFS the xattrs are often stored outside
of the inode so it's a little bit like doing an `open()+read()`. Plus there's
the LSM overhead, etc.

The thing is that for rpm-ostree's package layering use case, we
basically always want to treat the on-disk state as canonical.  (There's
a subtle case here if one does overrides for something that contains
policy but we'll fix that).

Anyways, so we're in a state now where we do the slow but correct thing by
default, which seems sane. But let's allow the app to opt-in to telling us
"really trust devino". The difference between a `stat()` + hash table lookup
versus the full xattr load on my test case of `rpm-ostree install
./tree-1.7.0-10.fc27.x86_64.rpm` is absolutely dramatic; consistently on the
order of 10s without this support, and <1s with (800ms).

Joaquim Rocha a1745e1a79 lib/remote: Add a method to return the URL
When using dynamic remotes (LAN and USB), we cannot use their name with
the common remote related ops (ostree_repo_remote_...) because ostree
doesn't keep this type of remotes in its internal hash table.
Unfortunately this means that we cannot access the URL of those remotes
either (in order to e.g. set the right URL for those remotes in
Flatpak).

Since the URL is actually stored in a key file that belongs to the
OstreeRemote, then we can simply allow users access to it through a
getter.

So this patch adds a method that allows to return the URL directly from
the OstreeRemote without having to go through the OstreeRepo.

deployment and did a `--require-static-deltas` pull, i.e. the initial
state.

I cleaned up our "find static delta state" function to return an enumeration,
and extended it with an "already have the commit" state.  A problem
I then hit is that we've historically fetched detached metadata for
non-delta pulls, even if the commit hasn't changed.  I decided not to
do that for `--require-static-deltas` pulls for now; otherwise the
code gets notably more complex.
